Rendered to 6 significant figures.

Formula

Formula
BTU/hr = BTU/s × 3600

Multiply any value in British thermal units per second by 3600 to obtain the value in British thermal units per hour.

Worked example

Convert 1 BTU/s to BTU/hr.

  1. 01Start with 1 BTU/s.
  2. 02Multiply by the conversion factor: 1 × 3600 = 3600 BTU/hr.
Result1 BTU/s = 3600 BTU/hr

FAQ

What is the conversion factor from BTU/s to BTU/hr?
1 BTU/s equals 3600 BTU/hr. To convert, multiply the value in British thermal units per second by 3600.
How do I convert 1 BTU/s to BTU/hr?
1 BTU/s = 3600 BTU/hr. For any value, multiply by 3600.
How do I convert BTU/hr back to BTU/s?
Divide by the same factor — or equivalently, multiply by 0.0002777778. So 1 BTU/hr = 0.000277778 BTU/s.
When would I need to convert British thermal unit per second to British thermal unit per hour?
Power conversions are common when comparing motor ratings (often kW or hp), thermal duty (BTU/hr or kW), and utility consumption in mixed-unit projects.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
